The article presents data on the results of 525 pregnant women’ survey in the terms of 37–40 weeks of pregnancy. We revealed, that the level of 6-sulfatoximelatonin in morning urine in all placental groups was higher in seasons with the predominance of dark time of the day in dependence on the character of natural illumination and stereoisomery of placental complex: in rightoriented and ambilateral placental lateralization - in winter (when the light time of the day increases), and in leftoriented placental lateralization - in autumn ( when the light time of the day decreases). In right oriented functional systems «mother – placenta – fetus» resistance to stress and the level of sex-hormones was higher in autumn-winter seasons when the light time of the day decreases, in the left-oriented functional systems «mother – placenta – fetus» – in winter-spring time of the year, when the light time of the day increases. The level of testosteron didn’t differ significantly.
